Abstract

The phase regulating loop has a phase discriminator (PD), a loop filter (LF), an amplifier (PLV) and a voltage-controlled oscillator (VCO). The phase discriminator provides outputs of different polarity for positive and negative differences between the oscillator output frequency and the input signal clock frequency. A frequency discriminator series circuit (FD), with a low-pass pre-filter (TPVF) and a differentiator (DG) is connected between the output of the base discriminator and the output of the loop filter, for providing an auxiliary setting signal for the phase regulating loop, combined with the output of the loop filter via an adder (ADD).
